HI. I am currently looking into which MVHR unit I should get for a small house, refitted and think about the Blauberg BLAKOMFORT-ULTRA-D105-A or the Boulder DHV-04/100B. I like with the Blauberg that it has three speed options, is quite silent ( low speed), the max 76% heat recovery and the included warranty of 5 years. But it does not offer any automatic control unit to attach. The Boulder is a bit cheaper and just offers 3 years warranty and max 70% heat recovery. They do not give any db for the low speed function, but I have contacted them regarding this. But therefore a separate control unit is available to adjust the speed according to the humidity. Somehow it looks so to me that the Blauberg is more popular. Anyone here which has them and would like to share their experience ? And of course any other input is more than welcome. Is there maybe another MVHR unit which I oversee, but is rather reasonably priced and better than those two? Thank you in advance for your thoughts and help. Cheers Manfred

Hi. We have an old house which is currently under renovation with a small new extension plus we take out downstairs the plaster and ceiling and create a large open kitchen Livingroom area. With a very large (1000l) aquarium the humidity is always too high. So far we had a mvhr from suedwind in the wall, but its performance was not very great, still every morning we have around 70% humidity and open all doors and windows. Without it running 80% I wonder if there is a reasonably priced mvhr solution to put in the extension loft which will take mainly out the humidity in the living / kitchen room area, as that is where the tank is, or a wall mvhr from kair But then I read that they even recover the humidity, which is what I want to get rid of. So I wonder if I should instead install in the main loft a positive input ventilation, possibly with a heater to take the edge off on cold days. What do you think would handle the high humidity better please? Thank you for your help Manfred
